Do not take a discussion off-list without clearly stating that you're
doing that, please. If you want private advice, my rates are $125/hour;
I'd imagine Thomas would also charge you a consulting fee. I've added
TAG back to the CC list.

Assuming you're talking about non-critical messages, try turning off
SCSI debugging in the kernel config. In an extreme case, you can tweak
the module code itself (but this last one is something you'd have to do
every time you update your kernel.)

Not unless you send _all_ output on that terminal to "/dev/null". :)
What you're proposing is _still_ getting rid of all system messages, and
I keep telling you that it's a bad idea - and thus not likely to be
supported. Getting rid of the non-critical messages from one module, OK;
shutting down system messages in general, bad idea.
